To all whom it con-0cm Be it; known that we,-: RICHARD Lnsrnn WILCOX and CLIFFORD O. PETlTJnAN', citi-,

zens ofthe United States, residing at ,VVaterbury, in the county of Newv Haven and State of connecticut, have invented. certain new and useful Improvements in Connection Mechanisms, ,of which, the following" is a specification, reference 'beingha'd therein to the accompanying drawings. f

: ;This invention relatestoconneotion mech; anisms and more particularlyv to such mechanisms as are used for operatively joining a-toggle, a pitman or;- the like to a reciprocating member or the like. -This type of mechanism is commonly, used in upsetting ore-heading machines and therefore will be shown and described moreparticularly as it relates to such type, although not, limited thereto; Y I p 1 c ,It is the object of thisinyention, among other things,:to provide, an'improved conof thegate and pitman or toggle of a head nection mechanism thatinits construction and operation will, not require an exact alignment of-its parts, which will automatically adjust themselves, to sounite the reciprocating member with the or pitman, or I the like, that the strain on the connection therebetween will be reduced, to the minimum, and-the possibility of injury or-b'reakage of the connection mechanism or the. adjacent parts will be entirely eliminated, Amongother aimsand-objects of the invention may be 1 recited theprovision of mechanism of the character describedvwith a view to compactness, in which the construction is simple andefliciency of operation high. I v- The improvements in the details and arrangement of parts will-be apparent; from an inspection of J the accompanying drawings "in connection with the description hereinafter contained, and; wherein; aprevferred embodiment of the invention 18 dis- Referring to the drawlngs 1n which-like characters'of-reference designate like parts in the several figures; ,l

and, a resulting;unnecessary wear 'on "the Y 'Our improved ,Lmech'anisr'n his so fconstructedfand operated as to eliminateall possibility of such objectionable -.conditio ns, the block ad ust1ng itself relatively. to the gate irrespective several surfaces.

Heretofore it. has been the practice to con l of e": a lari yl QfEfi Q nect the toggle or pitman and. the gate block with means, rigidly secured v either-1 ftjh e toggle or pitman or], ltheblock itself and enerally by clamps, screws ,or' the glike.

This not only required-considerable labor and skill in the 'manufacture' of: the meChEtnism and the fitting thereof, A their vpriessure thereonwhilethedcrank, withYwhic'h; V

Theseobjectionable features ofathe'heretofore: common: practice ofconnec'tionsfof- 1 .this characterr are not present; intone im- .proved mechanism, f u

In the drawings or pitman, connected with and actuated generally f by a crank shaft; 10 designates the zgate of the usual type having the punch slide' 11 ,1 movable therein carrying a punch .block 12 with punches13therein. o

The construction andfoperatiom of the par-ts justldescribed are well knownTin the-1 art and therefore require lnolfurthencle-f scription hereimexcept as modified by our im rovements.

he gate block 15 is mounted so as to slide in the opening- 16v in the gate and has an angular rear face 17... In the hub 18 of the toggle or pitman is a bushing 19 through which and the gate block 15 projects the connection pin 20, so fitted as to rotate freely therein, and held against cndwise movement when assembled, by the dowelpin 21, which passes through the gate block '15 and an annular groove 22 in the pin.

This pin is free to rotate and move axially, during assembly, and there are no clampsor screws to be subjected to excessive strain. In manufacturing our device it is only necessaryto provide a straight cylindrical opening through the gate block and bushing andv a straight cylindricalpin of such size as to freely rotate therein. As this pin 20 can be placed in the opening made to receive it withthe fingers, no labor is required to assemble it.

The relative position of the gate block and gate isdetermined by a wedge heretofore made rectangular" in cross-section, thus necessitating a face on the gate that is at exactly a right angle with the sides of the gate, to produce which requires both skill and labor. We have designed a wedge mechanism that entirely eliminates this and objections to the old form of wedge mechanisms and the accurate alignment of the several faces is not requisite.

In the drawings, 23 designates the wedge whichis cylindrical in cross-section having a; Hat: angular face 24 upon one side thereof,

which contacts with the angular rear face 17 of the gate block.

The gate 10 is provided with a cylindric a l opening 25 of substantially the same dji'ame ter as that: of the wedge 23, and through which the latter moves inv the adjustment of the block. The curved back 26 f the wedge isincontact with the curved wall of the opening 25 substantially as shown in Figure 3". This wedge is provided with the usual head 27 which is tapped slightly to move the wedge downivard'ly, the screw 28' being adjusted to permit this motion, In the adjusted position of the gate the screw 28 which impinges against the button 29, prevents further movement of the wedge, and the gate block is held rigidly by the screw 30 that is thread'edthrough a lug 31 uponthe gate,and contactswith the face 32; in the gate block;

By this form of wedge mechanism the gate'block will adjust itself within the gate without cramping the latter in its ways, the wedge rotating freely about its 'axis'so as to accommodate this movement Minor changes and alterations may be made within our invention, aside from those have it understood that we do not limit ourselves to the exact construction herein shown and described, butc-laim all that iialls fairly within the spirit and scope of the appended claims. I v 7 What we claim as new and desire to secure by Letters. Patent, is:

1. In a device of the character described, a gate; a block movably mounted therein; and a wedge between said block and gate adjustable in relation to said gate to accommodate the relative positions of the block thereon.

2. In a device of the charaeter described, a gate; a block movably mountedtherein; and a wedge between said block and gate adjustable in relation to said gate and in its adjusted positions having rotatable contact therewith.

3. In a device o l the character described, a gate; a block movably mounted therein; a wedge between saidblock and gate, said wedge. having a curved contact with one ol said parts and a flat contact with theother of said parts.

4c. In. a deviceot' the character described; a gate; a block movably mounted therein; and a wedge between said block and gate having a flat face and acurved face.

5. In a device of the character described, a gate; a block movably mounted. therein;

6. In a device of the character described, a gate; a block movably mounted-1 therein; a wedge between said block and gate have ing a rotatable contact? with one of said parts when held in any of its. several posi tions; and means for adjusting said wedge parallel to its; length. I

7 In a device of hecharact'erdescribed, a gate; a block movably. mountedvtherein; a wedgebetween said gate and block; and means for holding said wedge: against moremeat in one direction when; in any ofits adjusted positions, the relation of said: gate, block and wedge being such that when said wedge is in any of its adjusted; posiitibns said block may rock in relation. to, said gate.

8. In a device of-the character described, a gate having a recess in one wall thereoifj; a block movablymounted: therein; and, a wedge between said block andgate having engagement with said. recess upon one side and with said block upon the opposite side.

9. In a device of the character described, i

a gate; a block movably mounted therein; a toggle or pitman; and means for connecting said toggle or pitman with said block,

comprislng a cylindrical pin projecting through said block and toggle or pitman and free to rotate therein.

- 11. In a device of the character described, a gate; a block 'movably mounted therein; a toggle or pitman; means for connecting said toggle or pitman with said block, comprising a cylindrical pin projecting through said block and toggle or pitman and free to rotate therein; and means for holding said pin against endwise movement 12.
